During the chat, Prince Harry also gave an insight into the chaos that surrounded his wife, Meghan Markle, revealing that “marrying a Prince or Princess is not all it’s made up to be.”
Asked by the fake ‘Greta’, he went on to share how he has coped with the pressure of dealing with the media over the years.
"For most, all of my life, I've always been part of a family and part of a country that is scared of the tabloid media because they have so much power and influence and no morals (chuckles),” reflected Harry.
"From the moment that I found a wife that was strong enough to be able to stand up for what we believe in together, has basically scared them so much that they've now come out incredibly angry, they've come out fighting, and all they will try and do now is try and destroy our reputation and try and, you know, sink us.”

Veering away from his own personal issues, the duke opened up about his views on climate change, comparing the climate crisis to a frog boiling slowly in hot water. Convinced he was speaking directly to Greta and her father, Harry commended the 17-year-old activist for her remarkable efforts, sharing that;
“Unfortunately the world is being led by some very sick people so the people like yourselves and younger generation are the ones that are going to make all the difference.”
As the conversation continued, the Duke of Sussex insisted that President Donald Trump had “blood on his hands” for ramping up coal production in the US.
“I think the mere fact that Donald Trump is pushing the coal industry is so big in America, he has blood on his hands.”
He also encouraged Greta to remain persistent in her fight for climate change action, despite Donald Trump’s alleged refusal to meet and discuss the issue.
“It’s far more important to have an open dialogue and have conversation with these people than not,” he said.
The Prince is yet to comment on the release of the phone hoax scandal.
